New Method Wellness combines pharmacogenetic testing with evidence-based therapy in the development of individualized treatment plans.
Pharmacogenomics is the study of how genes impact the body’s ability to metabolize certain medications, which may or may not produce severe allergic reactions. For health care providers, the goal of pharmacogenomics is to understand an individual’s family history and genetic make-up to determine the best treatment method for their patients.
While the science of pharmacogenomics is not new, pharmacogenetic testing also referred to as DNA Drug Sensitivity Testing or drug-gene testing, is a ground-breaking practice that may improve patient health outcomes in the future, though for now it is strictly monitored by the U.S. Food & Drug Administration (FDA).
The FDA makes it very clear how pharmacogenetic testing should be used. To date, there is insufficient data to establish the effectiveness of this type of testing, which is used by health care providers and consumers alike to determine the appropriateness of medication.
The FDA has issued a public warning to consumers with regard to direct-to-consumer products that make claims about predicting consumers’ reactions to certain drugs. Consumers are instructed to discuss test results with their physicians rather than making their own decisions about a drug. Health care providers received a stern warning about not relying solely on these test results for treatment decisions.
Why do some people have a severe allergic reaction to a drug while others have no reaction at all? This is based on a person’s genotype, which influences how the body metabolizes drugs. While individual genetic variants, or the genetic makeup of each individual, play a large role in the development of diseases and somatic responses to drugs, other factors that affect how a person’s body responds to drugs include lifestyle factors such as drug and alcohol use, environmental factors such as exposure to radiation and chemicals, and physiological factors such as gender, age, and liver function (Ahmed, Zhou, Zhou & Chen, 2016).
The body’s response to a drug, referred to as pharmacodynamics, depends on how long it takes for the body to absorb, metabolize and excrete the prescribed drug. The body produces enzymes that break down a drug, changing its chemical structure to make it easier for the body to excrete the medication.
The efficacy (and toxicity) of the drug depends on the speed at which the body metabolizes a certain medication. For some, their bodies may metabolize the drug too quickly before it has a chance to work at effective levels. For others who take the same medication, their bodies might metabolize too slowly, which means that toxins can build up in the body, causing a range of reactions from mild to life-threatening somatic responses.
The aim of pharmacogenetic testing is to avoid life-threatening reactions by using information that could help health care professionals predict treatment outcomes. Patients who are on multiple medications on a regular basis, or those who have had adverse reactions to a drug that resulted in hospitalization, may benefit from pharmacogenetic testing.
In addiction treatment, patients who have comorbid disorders such as substance use disorders, mental health disorders, and physiological disorders may be at risk for adverse reactions if they are taking multiple medications to address each health issue. Results derived from drug-gene testing can inform health care professionals about the appropriate medicine and dosage for a patient and possibly predict whether the patient will have a severe reaction to a certain drug.
Choosing the right medication for individuals suffering from depressive orders is a challenge for health care professionals. Approximately more than 40% of patients stop taking psychotropic medications within 90 days due to lack of response or negative side effects (Health Quality Ontario, 2017). Common side effects may include dry mouth, nausea, sexual dysfunction, drowsiness, and headaches.
Patients may also experience more serious side effects such as seizures and gastrointestinal bleeding. The problem with psychotropic medications is that they fail to achieve adequate effective responses in approximately 30% to 50% of patients who take prescribed medications for depression, anxiety and other related disorders (Arranz et al., 2019).
Findings from various studies show promises of pharmacogenetic interventions but with mixed results. One clinical study conducted by Arranz and associates showed that pharmacogenetic interventions can be useful in improving the safety of psychotropic treatments by reducing negative side effects (Arranz et al., 2019).
One of the current limitations of pharmacogenetic testing is that one single test cannot determine how an individual will respond to all medications; more than one test may be required if a patient is taking multiple medications (Mayo Clinic, 2019). Due to the limited availability of pharmacogenetic tests, patients must consult their health care professionals to see if they need a drug sensitivity test before they begin treatment (Mayo Clinic, 2019).
A genetic swab test has been incorporated at admission to New Method Wellness’s treatment program, which will help guide members of the psychiatric and medical team in precision medicine. The pharmacogenetic test is not meant to be used as a substitute for medical advice but merely as a tool intended to optimize treatment outcomes.
Providing quality client care means giving clients access to clinical tools and support that will facilitate their recovery faster and more effectively. Always at the forefront of medical research and advancement, New Method Wellness brings the future of addiction treatment to its clients.

ACCREDITED BY:
We firmly believe that the internet should be available and accessible to anyone, and are committed to providing a website that is accessible to the widest possible audience, regardless of circumstance and ability.
To fulfill this, we aim to adhere as strictly as possible to the World Wide Web Consortium’s (W3C) Web Content Accessibility Guidelines 2.1 (WCAG 2.1) at the AA level. These guidelines explain how to make web content accessible to people with a wide array of disabilities. Complying with those guidelines helps us ensure that the website is accessible to all people: blind people, people with motor impairments, visual impairment, cognitive disabilities, and more.
This website utilizes various technologies that are meant to make it as accessible as possible at all times. We utilize an accessibility interface that allows persons with specific disabilities to adjust the website’s UI (user interface) and design it to their personal needs.
Additionally, the website utilizes an AI-based application that runs in the background and optimizes its accessibility level constantly. This application remediates the website’s HTML, adapts Its functionality and behavior for screen-readers used by the blind users, and for keyboard functions used by individuals with motor impairments.
If you’ve found a malfunction or have ideas for improvement, we’ll be happy to hear from you. You can reach out to the website’s operators by using the following email juanita@newmethodwellness.com
Our website implements the ARIA attributes (Accessible Rich Internet Applications) technique, alongside various different behavioral changes, to ensure blind users visiting with screen-readers are able to read, comprehend, and enjoy the website’s functions. As soon as a user with a screen-reader enters your site, they immediately receive a prompt to enter the Screen-Reader Profile so they can browse and operate your site effectively. Here’s how our website covers some of the most important screen-reader requirements, alongside console screenshots of code examples:
Screen-reader optimization: we run a background process that learns the website’s components from top to bottom, to ensure ongoing compliance even when updating the website. In this process, we provide screen-readers with meaningful data using the ARIA set of attributes. For example, we provide accurate form labels; descriptions for actionable icons (social media icons, search icons, cart icons, etc.); validation guidance for form inputs; element roles such as buttons, menus, modal dialogues (popups), and others. Additionally, the background process scans all of the website’s images and provides an accurate and meaningful image-object-recognition-based description as an ALT (alternate text) tag for images that are not described. It will also extract texts that are embedded within the image, using an OCR (optical character recognition) technology. To turn on screen-reader adjustments at any time, users need only to press the Alt+1 keyboard combination. Screen-reader users also get automatic announcements to turn the Screen-reader mode on as soon as they enter the website.
These adjustments are compatible with all popular screen readers, including JAWS and NVDA.
Keyboard navigation optimization: The background process also adjusts the website’s HTML, and adds various behaviors using JavaScript code to make the website operable by the keyboard. This includes the ability to navigate the website using the Tab and Shift+Tab keys, operate dropdowns with the arrow keys, close them with Esc, trigger buttons and links using the Enter key, navigate between radio and checkbox elements using the arrow keys, and fill them in with the Spacebar or Enter key.Additionally, keyboard users will find quick-navigation and content-skip menus, available at any time by clicking Alt+1, or as the first elements of the site while navigating with the keyboard. The background process also handles triggered popups by moving the keyboard focus towards them as soon as they appear, and not allow the focus drift outside of it.
Users can also use shortcuts such as “M” (menus), “H” (headings), “F” (forms), “B” (buttons), and “G” (graphics) to jump to specific elements.
We aim to support the widest array of browsers and assistive technologies as possible, so our users can choose the best fitting tools for them, with as few limitations as possible. Therefore, we have worked very hard to be able to support all major systems that comprise over 95% of the user market share including Google Chrome, Mozilla Firefox, Apple Safari, Opera and Microsoft Edge, JAWS and NVDA (screen readers), both for Windows and for MAC users.
Despite our very best efforts to allow anybody to adjust the website to their needs, there may still be pages or sections that are not fully accessible, are in the process of becoming accessible, or are lacking an adequate technological solution to make them accessible. Still, we are continually improving our accessibility, adding, updating and improving its options and features, and developing and adopting new technologies. All this is meant to reach the optimal level of accessibility, following technological advancements. For any assistance, please reach out to juanita@newmethodwellness.com
